Although STM8 has complete functions, insufficient space is often a problem. Either .text overflow or .bss overflow, which is a headache. Here are some optimization solutions to make full use of space:
1. Under Project settings, C Compiler, Optimizations select Customize
The key is to select Split Functions.
This means that you only compile the functions you use, otherwise the compiler will stupidly compile all the functions in the C file you use, and of course there will not be enough space!
2. Go to Linker and select Input in Category.
Then see which one is not enough and set the value larger.
For example, my project shows .bss overflow (too many variables are defined), so I change the RAM from 0x1FF to 0x250.
